Tishitu's video: 6 Ziegler Nichols Tuning Method: PID Part-1

This tutorial video teaches about the method Ziegler-Nichols of PID tuning for the control system. Its effect also discusses on MATLAB platform. Ziegler Nichols developing two techniques in 1940 for the tuning of the PID controller. The method based on direct adjustment of gain parameters, and acquire information from the open-loop step response to evaluate the controller parameters. Ziegler Nichols defines the table-based calculation part, the value of the table finalized after the lots of exercises done on the industrial process. The critical value of Gain, Kcr, and corresponding to it, Pcr defines the PID controller parameters. Evaluation of Kcr and Pcr, Routh's Hurwitz stability criterion-based method is useful. Routh's Hurwitz defines a routh array by the given characteristic equation. Denominator Polynomial of transfer function defines the characteristic equation. Coefficients of characteristics equation create the base of routh array and further elements of array evaluated by using the given coefficients. he value of the first column of the routh array define the stability of the system. On the concept of stability, Routh Hurwitz helps out to calculate the value of Kcr and Pcr. PID controller parameters are related to Kcr and Pcr according to the table defined by Zieger Nichols. Use that values for designing of PID controller for a particular system.
